请问这是什么错误啊，我用的是ATMEGA128，CH375，ICCAVR，包含库文件和头文件后编译出现错误： !ERROR file 'CH375MAI.o': undefined symbol 'push_gset1' !ERROR file 'CH375MAI.o': undefined symbol 'push_gset2' !ERROR file 'CH375MAI.o': undefined symbol 'push_gset3' !ERROR file 'CH375MAI.o': undefined symbol 'push_gset4' !ERROR file 'CH375SEC.o': undefined symbol 'push_gset5' !ERROR file 'CH375MAI.o': undefined symbol 'pop_gset1' !ERROR file 'CH375MAI.o': undefined symbol 'pop_gset2' !ERROR file 'CH375MAI.o': undefined symbol 'pop_gset3' !ERROR file 'CH375MAI.o': undefined symbol 'pop_gset4' !ERROR file 'CH375SEC.o': undefined symbol 'pop_gset5'

ICCAVR的版本是多少？你看一下CH375库的头文件，版本是否一致。

是ICC7.22的，头文件里是这个吧 ** USB Host File Interface for CH375 ** ** TC2.0@PC, ICCAVR_6.31@AVR ** 哦，懂了，那请问有没有针对7.22版本的头文件啊，我现在不可能换开发环境了

有一个7.13版本的库，可以试验一下？ 要么可以使用CH376芯片
